Platform Overview
What is Omni Chat Stack?
Omni Chat Stack is a WhatsApp business messaging platform: a customer communication platform built for small teams. It connects your existing WhatsApp Business number, along with Instagram, Facebook, email and webchat, into one shared inbox your whole team works from. AI answers routine questions in six languages and can answer your WhatsApp calls.
Every conversation, one workspace
Select a channel below to see how it connects your customers with your support team.
Instagram Direct
Bring Instagram Direct messages and story replies into the same workspace as your other customer channels.
Facebook Messenger
Connect your Facebook Page so agents can answer Messenger conversations from the shared inbox.
Route customer support emails into the same shared inbox alongside your live messaging channels.
Live Chat / Webchat
Add the web chat widget to your site and route every visitor conversation to the right agent or AI.
Platform in Action
Every channel in one inbox, assigned automatically.
AI answers in your customer’s language, then hands over to your team.
Calls answered by AI, transferred live with a summary of the call.
Read rates, AI resolution and response times, on every plan.
Can multiple users share one WhatsApp Business number?
Yes. Every agent gets their own login to the same number, in one shared WhatsApp inbox. Incoming messages land in that inbox and each new conversation is assigned automatically, so every chat has a clear owner and nobody answers the same customer twice. Your customers still see one official number.
WhatsApp Coexistence
Your number doesn’t change
Omni Chat Stack uses official WhatsApp Coexistence, so you keep the number your customers already have saved and keep using the WhatsApp Business App on your phone. Your last six months of one-to-one chats sync into the shared inbox when you connect, and keep syncing both ways.
Omnichannel Workspace
WhatsApp, Instagram, Facebook, email, one inbox
Everything lands in one place, assigned automatically, so nothing gets missed during busy weeks. WhatsApp, Instagram, Facebook, email and webchat land in the same inbox, so nobody is guessing what a colleague already answered.
Broadcasts & Campaigns
Segmented, scheduled WhatsApp broadcasts on Meta-approved templates.
Automation & Flow Builder
Drag-and-drop reply flows that answer the questions you get every day.
Developer API
Send and receive WhatsApp messages from your own app, if you'd rather build than click.
Templates & Catalogue
Manage WhatsApp templates and show your products, right inside the chat.
AI Receptionist
Answers your WhatsApp calls in five languages, recognises the language the caller speaks, and transfers live to your team with a summary of the call.
WhatsApp Calling
Inbound and outbound WhatsApp calls from the same workspace, on the same number as your chats.

Frequently Asked Questions
Everything you need to know about the platform.
What is a business messaging platform?
A business messaging platform lets a company talk to customers on messaging apps such as WhatsApp, Instagram and Facebook from one shared workspace, with several people answering, automation and AI. Omni Chat Stack is a business messaging platform built around WhatsApp.
Is this the WhatsApp Business app?
No. Omni Chat Stack is a platform built on the official WhatsApp Business Platform (the WhatsApp Cloud API). You keep using your own WhatsApp number, and your whole team works it from one place, which the free WhatsApp Business app cannot do.
Can multiple people use one WhatsApp number?
Yes. Your whole team logs in separately and works the same WhatsApp number together, with new conversations assigned automatically.
Do I have to change my WhatsApp number?
No. Official WhatsApp Coexistence lets you keep your number and keep using the WhatsApp Business App, while your team works from the shared inbox.
What happens to my existing chats?
Your last six months of one-to-one chats sync in when you connect, and keep syncing both ways from then on.
What languages does the AI support?
AI chat answers in six languages: English, Urdu, Roman Urdu, Arabic, Spanish and Portuguese. The AI receptionist answers calls in five: English, Urdu, Arabic, Spanish and Portuguese.
Can the AI answer phone calls?
Yes. The AI receptionist answers calls to your WhatsApp Business number in five languages, recognising the language the caller speaks. When a caller needs a person it transfers live and passes across a summary of the call so far. 100 voice agent minutes a month are included.
Do I need the WhatsApp Business API to use it?
Your account runs on the official WhatsApp Business Platform, and Omni Chat Stack sets that up for you as a Meta Tech Provider. There is nothing to apply for separately.
Can I send bulk WhatsApp messages?
Yes. Broadcasts and campaigns send approved template messages to a segment of your contacts, immediately or scheduled, on every plan.
Can I use it as a WhatsApp CRM?
Your contacts, their conversation history across all five channels and your team’s replies live in one place, so most small teams use it as their WhatsApp CRM. It is a messaging platform rather than a full sales CRM.
Can I automate WhatsApp replies?
Yes. Drag-and-drop bot flows handle common questions and route conversations, and the AI chatbot answers from your own content on AI plans.
Does it work with Click-to-WhatsApp ads?
Yes. Conversations started from a Click-to-WhatsApp ad arrive in the same shared inbox, inside Meta’s free 72-hour entry window.
Can I see reports on my team and my AI?
Yes, on every plan. Reporting shows messages received, how many chats the AI resolved, how many your team handled and your average response time, plus read rates and resolution channel by channel, for any date range.
Is the first agent really free?
Yes, on Starter, with no card. Each additional agent is $10 a month.
Do you add a markup on WhatsApp messages?
No. Meta bills you directly at Meta’s published rate and Omni Chat Stack adds 0% markup on every plan.
